Hezbollah denied on Thursday its involvement in this week’s attacks against Israeli missions in India and Georgia as Israel called on the United Nations to condemn the attacks it said were plotted by Iran and its ally in Lebanon.

“I assure you that Hezbollah has nothing to do with this,” Hezbollah leader Hassan Nasrallah told supporters. Israel accused Iran and Hezbollah of being behind twin bomb attacks on Israeli embassy staff in India and Georgia on Monday, wounding four people. Tehran also denied the Israeli accusations.

Nasrallah was speaking at an event marking the fourth anniversary of the assassination of its military commander Imad Moughniyah. The Shi’ite group accused Israel of killing Moughniyah in a car bomb in Syria and has vowed revenge.

Israel has denied involvement, and said that it has since foiled several Hezbollah attempts to kidnap Israelis abroad.

Nasrallah reiterated the group’s vow to respond to Moughniyah’s killing: “As long as there is blood in the veins of any (member) of Hezbollah (then) the day when we will avenge the killing of Imad Moughniyah will come.”

Israel on Thursday strongly urged the U.N. Security Council to formally condemn the attacks against its diplomatic staff, hitting out at the world body for dragging its feet on the issue.

“The Security Council should have condemned these attacks immediately,” said Ron Prosor, the Israeli ambassador to the United Nations.

“Israel expects it to issue a clear condemnation today, without any further delay or equivocation,” he said in a letter that was sent to U.N. Secretary General Ban Ki-moon and circulated by the Israeli mission.

Prosor hit out at what he said was a “terror campaign that Iran and its proxy, Hezbollah, have launched against Israeli targets.”

Israeli Prime Minister Benjamin Netanyahu has said the recent plots were coordinated by Iran and Hezbollah.

“The Council must also address this threat by considering active steps against Iran, Hezbollah and their terrorist infrastructure worldwide,” Prosor said.

Hezbollah fought against Israel in a 34-day war in 2006 after the group captured two Israeli soldiers in a cross-border raid. Some 1,200 people in Lebanon, mostly civilians, were killed and 160 Israelis, mostly soldiers, died.
